<a name="id-1.3.40.8.3.6.4"></a><h2>Description</h2>
<p>This class is a wrapper that pretends to work exactly like <a class="link" href="classboost_1_1typeindex_1_1stl__type__index.html" title="Class stl_type_index">stl_type_index</a>, but does not require RTTI support. <span class="bold"><strong>For</strong></span> <span class="bold"><strong>description</strong></span> <span class="bold"><strong>of</strong></span> <span class="bold"><strong>functions</strong></span> <span class="bold"><strong>see</strong></span> <a class="link" href="classboost_1_1typeindex_1_1type__index__facade.html" title="Class template type_index_facade">type_index_facade</a>.</p>
<p>This class on C++14 compatible compilers has following functions marked as constexpr:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>default constructor</p></li>
<li class="listitem"><p>copy constructors and assignemnt operations</p></li>
<li class="listitem"><p>class methods: name(), before(const ctti_type_index&amp; rhs), equal(const ctti_type_index&amp; rhs)</p></li>
<li class="listitem"><p>static methods type_id&lt;T&gt;(), type_id_with_cvr&lt;T&gt;()</p></li>
<li class="listitem"><p>comparison operators</p></li>
</ul></div>
<p>
</p>
<p>This class produces slightly longer type names, so consider using <a class="link" href="classboost_1_1typeindex_1_1stl__type__index.html" title="Class stl_type_index">stl_type_index</a> in situations when typeid() is working. </p>
